These Ultra Sil dry sacks are lightweight and very robust. Not as light as the Nano’s but far from heavy. I’ve used these bags to keep my stuff dry in my backpack and they work!! Waaaaay better than plastic zipper bags and plastic trash bags. I bought several different sizes in different colors to help organize my gear better. No regrets here. Highly recommend these dry sacks.

I now use this as my main interior sack instead of a pack liner. It's not only useful to stay organized, but it's so much better than using the noisy plastic pack liner, especially when you are packing up and getting out of camp quietly. It's much faster compared to struggling with a plastic pack liner too, as the ultra sil just slips right into my 55L backpack easily. The dry sack does exactly what it does, and I haven't had an issue with moisture leaking inside.

HEADS UP - this isn't the kindest review courtesy of my lack of sleep. I hope this comes as helpful critique that ensures the future implementation of customer design is the highest quality possible but I'm sure with my current position and short fuse this is going to be a rough read.After 6 nights on this pad I hate this product and cannot stand to take it on the AT or any future adventure. I know y'all put great effort into the engineering but by God this is the worst mat I've ever slept on. I prefer to sleep on the tent floor.The sheer noise it makes was enough to have woken up my fellow campers and the lack of traction on it creates such an uncomfortable balancing act just to stay onboard the mat I felt I was riding a lubed up surfboard on a gliding magic ... MoreHEADS UP - this isn't the kindest review courtesy of my lack of sleep.

I prefer to sleep on the tent floor.The sheer noise it makes was enough to have woken up my fellow campers and the lack of traction on it creates such an uncomfortable balancing act just to stay onboard the mat I felt I was riding a lubed up surfboard on a gliding magic carpet underneath me (Not the best analogy but bear with me and my lack of any sleep).Suggestions: (a) either impose a full coat of more traction holding fabric along the entire surface or (b) patches/lines of far more tractive force creating material in a pattern throughout the pad.All in all, I regret buying this twice for my wife & I - we both desperately want to return these things but have passed your 60 day return policy as we ordered it while abroad and the biggest regret I have is having to now deal with reselling it on FB Marketplace.I apologize for the rant but it is an honest review and again, I hope it helps with future designs.
